Scarification tool

摘要

The scarification tool comprises a carrier blade with a handle (2), a part (3) for receiving and holding the blade, and a closure device (6). The part for receiving and holding the blade comprises a guide support with a curved surface (4) for receiving a lower surface (5) of the blade, and a longitudinal wall for transversely retaining the blade into a slot in a longitudinal center of the blade. The closure device is equipped with a unit for retention of the blade with support segment provided on an upper face of the blade and having a curvature. The scarification tool comprises a carrier blade with a handle (2), a part (3) for receiving and holding the blade, and a closure device (6). The part for receiving and holding the blade comprises a guide support with a curved surface (4) for receiving a lower surface (5) of the blade, and a longitudinal wall for transversely retaining the blade into a slot in a longitudinal center of the blade. The closure device is equipped with a unit for retention of the blade with support segment provided on an upper face of the blade and having a curvature additional to the curvature of the curved surface, and articulated on the blade in an intermediate zone between the handle and the blade receiving and holding part. The closure device and the intermediate zone comprise additional units for locking the closure device, and fastening units to force the blade between the receiving and holding part and the closure device according to the curvature of the curved surface. The centering wall includes a bulge forming a longitudinal restraint column of the blade located in wider area of the blade. The fastening units comprise protrusions or spurs disposed on locking sides of the receiving part and on walls of the locking sides of the closure device, where the walls extend from a side opposite to the support segments. The opposite walls of the closure are parallel flanges connected by a cross-piece forming an axis of torsion of wings under the action of pressure, where the twisting of the wings is carried out to disengage the fastening unit to ensure the closure and release of the blade. The closure device is adapted to rotate around a rear attachment axis in the housing of blade holder (1).
